A direct sequence code division multiple access (DS-CDMA) system combined with modified minimum energy (MME) coding is proposed and analyzed. The MME coding improves energy savings and error performance of minimum energy (ME) coding by partitioning a codeword into several subframes and using indicator bits. The results show that the proposed system clearly outperforms DS-CDMA systems with or without ME coding in terms of energy consumption and bit error rate. This indicates that combining MME coding and DS-CDMA is an attractive choice for wireless sensor networks.
